Specification of Letters Patent.

Patented Apr. 1,1919.

To all whom it may concern:

Be it known that 1, WILLIAM EATON PER- RYGLEAR, a citizen of the United States, residing at Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stoves and furnaces and more particularly to that type of stove shown in my former Patent 1,239,514, issued Sept. 11, 1917 The object of this inventio-n'is to improve upon and simplify the construction shown therein.

One of the objects of the invention'is the provision of concentric grates independently operable, and, an improved arrangement thereof.

Still another feature of the invention resides in simplifying the means for preventing escape of the dust when the ash-pan is withdrawn.

Another object is to provide positive means to prevent withdrawal of the pan when the ash-exit is open. The invention.

further consists in the arrangements and combination'of parts thereof disclosed in the following specification and specifically set forth in the appended claims.

And while it is clear that the present drawings illustrate the preferred form of my invention, the same is not restrlcted thereto but may be changed in design, size and mode of operation within the scope of such claims.

Referring to the drawings Figure 1 1s a sectional elevation showing the general arrangement of the stove; Fig. 2 is a section on line 2-2 of Fig. 1 in the direction of the arrows; Fig. 3 is a detail view of the operating lever and its shaft connection; Flgs. 4, 5 and 6, are detailed views showing the an locking device. Fig. 7 is an enlarged p an view of. he grate construction, and Fig. 8 is a vertical section of Fig. 7

The stove or furnace which may be of any type, is provided with a grate preferably consisting of outer and inner members. The outer member comprises an outer wheelshaped structure having a rim 2 joined to a hub 3, by means of ra ial spoke-like mem bore 4 which as illustrated are humped cen trally as at 5 and rounded laterally across the top thereof to facilitate the passages of the ashes through said members when the grate is moved. The hub 3 is provided with a central recess 6 and a seat 7 on which rests the inner grate member 8 which may take various forms but herein is shown as provided with radially spaced arms or spokes 9 emanating from a central hub 10, the underside of which is provided with a recessed collar 11. Arm 9 shapes or curves radially and laterally downwardly from the hub which construction also insures the easy passageof the grate member.

To provide means to operate the outer grate member the sameis preferably provided on the underside of the rim 2 with teeth 12 adapted to engage the teeth ofone or more pinions 13 journaled as'at14 in the furnace'wall. One of these pinions 15 is provided with a drive shaft 16 adapted to be turned in any manner. It isof course obvious that any type of gearing may be used and that the drawing contact neednot necessarily be at the exact location shown. If

desired, the grate maybe made of a single member and rotated by the central shaft 17 as illustrated. I

Means are also provided to independently operate the inner grate member 8. andthe particular form illustrated is a shaft 17 projecting into the recess of thecollar 11, and preferably provided with a yieldable connection of the pin andv notch type so that the shaft can rotate-relatively to the inner grate by having the pin thereon ride out ofth'e notch in said collar 11 in case the grate is prevented from rotation by clogging.

Arranged below the grate is a draft'device which preferably consists ofv a series of. openings 18 in the furnace wall at this point. And adapted to cooperate therewith is an annulus 19 provided with similar shaped openings 20 so that by oscillating this ringshaped member the draft may be opened, closed or partially closed. It is also apparent that any convenient arrangement of draft device may be used in this connection. In order to provide a suitable bearing for the vertical shaft 17 the walls of the furnace are provided with one or more inwardly curved ribs 21 formed with a centrally arranged bearing 22 through which the shaft 17 is journaled.

Fixed to said shaft 17 in any desired manner and immediately below said journal 22- two of the sides thereof are cut away to provide the opposed flat faces 26.

Projecting through a slot 27 in the oscillatable annulus 19, and also passing through a much longer slot 28 in the wall of the furme sure lever 29 provided on its inner end with a yoke-in the shape of an annulus which is adapted to rest on the ledge 24 and provided with a, circular portion 30 surrounding and freely fitting the mutilated circular studsor projection 25 so that moveinent (if the lever 29. in such position will not affectthe shaft 17, butwiljl oscillate the shaft his 19;". The walls of the yoke or annuhis project radially from the circular portion" thereof as at 31 to form a fiat-sided guide 32 to receive the flat faces of the ciroiflai stud25. so that when the lever is pushed inwardly thestud 25 will enter into the guide 32 on the" lever 29 in which position lateral 'movement of the lever will not only oscillate the draft annulus 19, but will alsoo'scillate" the shaft 17 to move the inner grate member.

'At" the lower portion of" the furnace the wallsthfe'reof are preferably flared inwardly at 33 to" provide an ash exit 34 which is adaptedto receive an ash-pan 35 of any suitable type.- In the present instance the latter; is shown as previded with an outwardly flaring mouth 36 adapted to make a dii'st pfoejf with the inwardly flaring mouth" 37 'of'the ash exit.

In, order to retain. the base in such position; and also. ermi't its facile withdrawal,

there: is pres ed the ash support or base 38, herein. shown of' any appropriate. design; 'a nd'adapted to be supported from the base frame, 39of'the furnace by means of the bracket members 40 which are pinned to a eirc lar cross bar 41 also pivotally mounted in the furnace walls as at 42.

Dependin from said base frame 39 is a springzc'at-cli 43 adapted to hold said base in its upper position to support the ash-pan, as shown in Fig. 6.

With this" construction when the catch is released the base" may-be lowered whence the mouth of the pan 35 will slip off the flared 'mouthof the ash-exit. 1

I, To the endfthat ashes may not fall upon the floor when the pan is withdrawn. there is provided a.closure for the ash exit which consists'ef a' perforated web 43 inserted into the low'er'por'tion of .the ash exit and central recessed to provide a journal for the low rifiostend of. the vertical shaft 17. To thezend of this shaft is fastened a cooperating shutter or ash exit closure 44 provided with spaced closing vanes 45, the upper faces of which slant laterally from a central ridge 46, whereby to direct the ashes be -low. Above the shutterand integral therewith, or fast to the shaft 17 is the ash agitator 47.

Means i also provided -for preventing the opening of said shutter except when the pan is in position and the same preferably comprises an arm 48 fast to shaft 41 and provided with a somewhat elongated locking pm 49 passing freely through the mouth of the. ash exit and adapted to'ente'r an aperture 50 in one of the shutter vanes 45 when the latter registers with the inwardly projected position of said locking pin, as shown in Fig; 4.

There is also provided means to prevent said pin from entering itsslot 50 in the vane many other but closed position, and in the present instance consisting of an'abutment or shoulder 51 arranged on the" shutter cir. cumferentially thereof and adapted tolie in the path of said locking pin 49 as the shutter 1 In the operation of the device, when it is desired 'to" regulate the draft, the lever 29 is pulled outwardly to disengage the flat-faced lug 25 from the guide 32 on the yoke, so that the shaft 17 will be unaffected, but engagei-nent of the lever with the slot 27 will move the draft annulus 19. When it is also desired to operate the inner grate member 18, the lever 29 is pushed in, whence the shaft 17 may be rotated thereby to move the grate. In any position other than extreme movement of the lever 29 to the right, as shown in dotted lines in Fig. 2, the ash exit closure will be open, more or less, and the ashes free to fall into the pan. It will of course be clear that when the grate is operated the draft will also be open to assist the agitation of "the fire.

en it is desired to remove the ash-pan the lever 29' must be forced to its extreme right, shown in dotted lines in Fig. 2, whence the ash-exit shutter will close, and the locking-pin 49 will automatically enter its aperture or notch 50 in the same, permitting the base to be free to swing downwardly and allow the pan to slide forwardly upon release of the spring catch.

Having thus described my invention what I claim as new and desire to secure by Letters Patentis v '1.
